Should have said "installing the NVidia libGL.so". - Greg On 04/13/2010 01:47 PM, Greg Couch wrote:
You are correct to suspect a Mesa library problem. We have worked around the remote display problems before by installing the NVidia (and dependencies) on the remote computer. If you don't want to override the system version of libGL.so, then put it in a different directory and set the LD_LIBRARY_PATH environment variable to that directory before running chimera.
If you want to try an isolate the part of OpenGL that is causing the problem, start chimera with the --debug-opengl command line option and press the Disable All button to disable many OpenGL features, and then Start Chimera. If opening a PDB file works, then you can experiment turning OpenGL features back on until chimera fails again. You can speed up the search if you're familiar with OpenGL and start chimera with the --debug command line option -- in that case, it should reliably fail in the same place and the error message should indicate the part of OpenGL that is causing problems.
As for running chimera on NX client, I didn't see any mention of OpenGL support on the NX Server feature page, so you're probably out of luck. If you want to display remotely on a Windows computer, you can install a X server that supports OpenGL, like Xming or Exceed 3D.

My older version of chimera x forwards with no problem; from the about ucsf chimera window its beta version 1 build 2064 2004/12/15 for linux2
We have upgraded the 32 and 64 bit version which run fine locally. but when we run from another computer with ssh either with -X, -Y, -XY , -o ForwardX11=yes frankel@graphics1 we always get a crashe after trying to do something (e.g fetch a pdb) with the same genral error message
frankel@graphics1:/home/frankel 102% /programs/chimera-1.4.1-x86_64/bin/chimera X Error of failed request: BadRequest (invalid request code or no such operation) Major opcode of failed request: 144 (GLX) Minor opcode of failed request: 181 () Serial number of failed request: 5374 Current serial number in output stream: 5379
(serial numbers may differ between runs) Can this be fixed? (We suspect it's a mesa library problem).
Also when running nx client, even the old version of chimera from crashes. I'll have to get the error message later, but does anyone have experience running over nx client?
we've gotten pymol, and vmd to work.
thanks Ken Frankel
